For the last several years, I've slept at most seven hours every night. If I went to bed at 11:00, I'd wake up at 6:00 and couldn't get back to sleep. A 10:30 bedtime meant waking at 5:30. This was true during the school year, spring break, the long summer break; whether I was at home or away.
One morning about a month ago, I was surprised to realize I'd slept eight hours. Was I getting sick? No, I was fine.
And then the same thing happened the next night, and then the next, and now eight hours is my new norm. Some nights it's even eight and a half!
This started happening at about the same time that I decided to take off one day a week. Clearly I'm feeling less pressure to get up and make the most out of my waking hours!
